SEIZAIKEN SR Batteries use silver oxide as the cathode,
zinc as the anode, and sodium hydroxide solution or
potassium hydroxide solution as the electrolyte. These
batteries offer a large capacity and stable voltage
characteristics. SEIZAIKEN Batteries are widely used in
products demanding high accuracy, such as quartz watches.

Batteries using pottasium hydroxide solution are most suit-
able for functions which consume relatively high current,
such as an alarm or backlight function incorporated into
digital quartz watches.
